STAMFORD -- A search warrant being served on a Vine Road home for health code violations and "blighted" conditions led to the property's investigation by the Police Department's bomb squad Wednesday afternoon.

Neighbor complaints to the Health Department about more than one family living in the house, located in a single-family residential neighborhood, along with other conditions led the department to obtain a search warrant for the home, Police Capt. Brian McElligott said.

Police and city Department of Public Safety, Health and Welfare officials descended on the house at about 11 a.m., and a call for the bomb squad was made about an hour later. At about the same time, animal control was called to remove two German shepherds from inside the home.

McElligott said suspicious substances were found in the home's basement and in the backyard. Police were concerned those substances, if combined with others, could become explosive, he said.

Because of those concerns, the bomb squad was called in to clear the home, McElligott said.

Police said federal agents have also been called in to inspect the suspicious substances.

One officer said the home was quite messy and the smell inside almost unbearable.

The code violation were related to single-room occupancy conditions at the house, McElligott said. The Police Department is seeking its own search warrant for the home, expecting to seize weapons such as shotguns, as well as computers and the substances, he said.

Police will continue to secure the home until the search warrant is executed, McElligott said.
